Hi All.

I'm really hoping someone can help me. I use a mac laptop and have been downloading .avi files and watching them on quicktime with no problems. Until recently...movies that I had watched before with no problems, I opened up and now I have sound but no video. This has happened to about half of my movies. I have the latest version of Quicktime and I have no clue what to do.

Can anyone out there help me?

Thanks in advance for your help.

Andi
